Role of Resonant -Points in the Transient Optical Response of Pumped Germanium
Amir Eskandari-asl, Giacomo Inzani, Matteo Lucchini +1
Pump-induced transient optical properties combine contributions from electronic states throughout the Brillouin zone, but the relative relevance of off-resonant and l-photon resona…
Controlling Ultrafast Excitations in Germanium:The Role of Pump-Pulse Parameters and Multi-Photon Resonances
Amir Eskandari-asl, Adolfo Avella
We employ the Dynamical Projective Operatorial Approach (DPOA) to investigate the ultrafast optical excitations of germanium under intense, ultrashort pump pulses. The method has v…
Controlling photo-excited electron-spin by light-polarization in ultrafast-pumped altermagnets
Amir Eskandari-asl, Jorge I. Facio, Oleg Janson +2
Altermagnets (AMs) constitute a novel class of spin-compensated materials in which the symmetry connecting opposite-spin sublattices involves a spatial rotation. Here, we uncover a…
Generalized Linear Response Theory for Pumped Systems and its Application to Transient Optical Properties
Amir Eskandari-asl, Adolfo Avella
We derive the two-time linear response theory for out-of-equilibrium pumped systems, generic pump-probe delays and probe frequencies. Such a theory enormously simplifies the numeri…
